Q: What does code P1693 mean?

DTC Detected In ECM Or PCM. P1693 on Chrysler vehicles means the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected a fault code stored in the other controller, typically the Transmission Control Module (TCM). The code itself is a messenger, not the actual fault, so the real problem lies in whichever module set the companion code.
